multicast application.....???

hi all....

i m assigned this job to test my network which comprises of 8 routers for multicasting (pim,dvmrp etc) but for this i need a multicast application(obviously..) can anybody tell me where i can get a good one (client and server) which works accross different networks???

Actually, I was a little motivated to write a little multicast client-server application
myself. The server sends a string once a second (XSleep[1]) to a multicast address.
I've set the TTL to 3 to enable small hops, if the routers support multicasting.
The clients join the multicast group to receive the string. The code does work
as well under Windows as Linux - just a few lines (headers) have to be modified.

This is for educational purposes only I tried to be as close to the "common
notation" as possible to simplify comparison with other source codes out there.

Do not forget to link the library WSock32.lib. If you want to read
more about multicasting, there is a pretty good introduction[2]
available. I would suggest to play with different settings (pim,...),
in particular with heavy load traffic. (Guus' link).
